Don't show back button on android toolbar

Question

Hi am developing an android application which has a toolbar and hamburger icon to open drawer. I have written below to implement toolbar.

xml file:

<android.support.v7.widget.Toolbar>

android:id="@+id/toolbar"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:background="@color/colorPrimary"

android:minHeight="?attr/actionBarSize">

</android.support.v7.widget.Toolbar>

Java file:

Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
        ((AppCompatActivity)getActivity()).setSupportActionBar(toolbar);
        ((AppCompatActivity)getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        ((AppCompatActivity)getActivity()).getSupportActionBar().setHomeButtonEnabled(true);

When I click on drawer layout, fragment opens and hamburger button changes to back arrow button.

I don't want this back arrow button. I want that irrespective of which fragment is selected there should always be hamburger icon.

Answer 1

remove this if you don't want any icon:

((AppCompatActivity)getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(false);

If you want to set custom icon then add this:

 ((AppCompatActivity)getActivity()).getSupportActionBar().setHomeAsUpIndicator(R.mipmap.backarrow);
